Abstract
The utility model relates to a zipper puller, in particular to the zipper puller which can be reliably locked. The zipper puller comprises a zipper puller body, a pulling piece, a lock core, a cap and a spring leaf, wherein the zipper puller body comprises an upper wing plate, a lower wing plate and a guide pole which is connected between the upper wing plate and the lower wing plate; the tail ends of the upper wing plate and the lower wing plate take rectangular shapes, and the head parts of the upper wing plate and the lower plate take Y shapes which expand outwards; an upper flange which is bent downwards is arranged at the lateral side of the upper wing plate, and a lower flange which is bent upwards is arranged at the lateral side of the lower wing plate; a zipper channel is formed through the encirclement of the upper wing plate, the lower wing plate, the upper flange and the lower flange; the lock core is arranged on the upper wing plate and under the cap, and a lock tongue on the lock core passes through the upper wing plate and is positioned in the zipper channel; and the guide pole is positioned on a medial axis of the zipper channel. The zipper puller is characterized in that the zipper channel is positioned at one side of the medial axis of the zipper puller body, therefore, the distance between the lock tongue and the medial axis of the zipper channel is enlarged, and the lock tongue can be reliably blocked at a position of a chain tooth head, which is near to a tooth chain belt, thereby the locking is more reliable, and the lock sliding can not happen easily.
Description
Technical field
The utility model relates to a kind of slider of zipper fastener, especially the slider of zipper fastener of positive lock.
Background technology
Slider of zipper fastener is one of major part that constitutes by slide fastener, common slider of zipper fastener is by the slider of zipper fastener body, pulling-on piece, lock core, block and spring leaf constitute, wherein the slider of zipper fastener body comprises upper flange, lower wing plate and be connected upper flange and lower wing plate between lead, it is rectangle that upper flange and lower wing plate are tail end, the Y shape that head expands outwardly, the side of upper flange is provided with the upper flange of downward bending, the side of lower wing plate is provided with the upwards lower flange of bending, the slide fastener passage is by upper flange, lower wing plate and upper flange and lower flange are around forming, lock core be installed in upper flange above, below the block, dead bolt on the lock core passes upper flange and is arranged in the slide fastener passage, and lead is positioned on the axis of slide fastener passage.The slide fastener passage of this slider of zipper fastener is positioned on the axis of slider of zipper fastener body, that is to say that the slide fastener passage overlaps with the axis of slider of zipper fastener body, and dead bolt is positioned at this axis one side, and when unclamping pulling-on piece, dead bolt stretches out, be stuck in the slit of sprocket, but owing to be subjected to the restriction of lock core and capping structure, the side-play amount of the relative axis of dead bolt is too little, and dead bolt can only be stuck in the edge of sprocket head in the time of locking, locking is also unreliable, slightly once firmly being easy to sliding lock.
Summary of the invention
The purpose of this utility model provides a kind of on the basis of existing structure, change little, can make full use of the existing resources of production, the slider of zipper fastener of positive lock.
For achieving the above object, the utility model adopts following technical scheme:
The slider of zipper fastener of positive lock described in the utility model, comprise the slider of zipper fastener body, pulling-on piece, lock core, block, spring leaf, wherein the slider of zipper fastener body comprises upper flange, lower wing plate and be connected upper flange and lower wing plate between lead, it is rectangle that upper flange and lower wing plate are tail end, the Y shape that head expands outwardly, the side of upper flange is provided with the upper flange of downward bending, the side of lower wing plate is provided with the upwards lower flange of bending, the slide fastener passage is by upper flange, lower wing plate and upper flange and lower flange are around forming, lock core be installed in upper flange above, below the block, dead bolt on the lock core passes upper flange and is arranged in the slide fastener passage, lead is positioned on the axis of slide fastener passage, it is characterized in that: the slide fastener passage is positioned at a side of the axis of slider of zipper fastener body.
Adopt after the technique scheme, enlarged the distance between dead bolt and the slide fastener passage axis, make dead bolt can be stuck in the nearly tooth chain belt of sprocket head rest position reliably, make locking more reliable, be not easy sliding lock.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the left view of Fig. 1 embodiment;
Fig. 3 is the structural representation of another embodiment of the utility model.
The specific embodiment
As shown in drawings, the slider of zipper fastener of positive lock described in the utility model comprises slider of zipper fastener body 1, pulling-on piece 2, lock core 3, block 4, spring leaf 7, wherein slider of zipper fastener body 1 comprises upper flange 11, lower wing plate 12 and be connected upper flange 11 and lower wing plate 12 between lead 13, it is rectangle that upper flange 11 and lower wing plate 12 are tail end, the Y shape that head expands outwardly, the side of upper flange 11 is provided with the upper flange 14 of downward bending, the side of lower wing plate 12 is provided with the upwards lower flange 15 of bending, slide fastener passage 5 is by upper flange 11, lower wing plate 12 and upper flange 14 and lower flange 15 are around forming, lock core 3 be installed in upper flange 11 above, below the block 4, dead bolt 31 on the lock core 3 passes upper flange 11 and is arranged in slide fastener passage 5, as shown in Figure 2, the position of dead bolt 31 is on the right side of slider of zipper fastener body 1 axis, and slide fastener passage 5 is positioned at the left side of the axis of slider of zipper fastener body 1.Lead 13 is positioned on the axis of slide fastener passage 5.Certainly, also can be as shown in Figure 3, the position of dead bolt 31 is in the left side of slider of zipper fastener body 1 axis, and slide fastener passage 5 is positioned at the right side of the axis of slider of zipper fastener body 1.
The utility model is arranged on slide fastener passage 5 side of the axis of slider of zipper fastener body 1, has enlarged the distance between dead bolt 31 and slide fastener passage 5 axis, makes dead bolt can be stuck in the nearly tooth chain belt of sprocket head rest position reliably, makes locking more reliable, is not easy sliding lock.
